With this build, we have a massive 59-meter stomp lasting 10 seconds along with a base 3000 hp Iron Skin. We take [Flow] to increase the number of stomps that we can "save up" to use at any time. We aren't taking [Vitality] because [Rhino]'s Iron Skin makes us invincible and it scales off of armor. Before you use your iron skin in a mission look for a group of enemies (I usually look for 3+) and charge through them with your 1, this will increase your armor even more.
If you're using the recommended arcanes make sure they proc before you charge through the enemies.
